Larimar is a rare variety of Pectolite, formerly Ratholita. It is a hydrated silicate acid and sodium calsio widely available in the world, we can find deposits of this mineral in distant parts of the world like USA, Canada, England, Scotland, India, Austria and others. This variety differs from all Pectolitas the world for its color, which comes from the copper, its hues range from dark blue to intense blue light and so does the number of marbled green and it can present.

In the only locality where Larimar appears in the earth's crust in Porvincia Barahona, southwest of the Dominican Republic. The Larimar's mine is found in the town of Los Chupaderos, about 10 km in the mountains near the city of Barahona. It is now the place where the larimar is the most abundant.

History: In 1916, according to historical data collected by the mining authorities Dominican priest Miguel Domingo Fuertes Loren who was then parish priest of Barahona, was the first to discover the blue rock. On 22 November the same year, he requested permission to explore and exploit the mine, but this was rejected because the country was not known this kind of Pectolite.In 1974 on a beach off the coast of Barahona, Miguel Mendez and Norman Rilling, a Peace Corps volunteer, rediscovered the larimar. The locals who thought that this rock came from the sea, called Roca Azul. However, your current nickname is owed to Méndez, which to attach the name of his daughter, called Larissa and the word sea, water colors of the Caribbean Sea where it was found, formed the word Lari-Mar. The few remains were found rocks that had been washed to sea by the River Bahoruco. After a search, found the source rocks, which became the mine's Chupaderos, which is the same place as before the priest had found in 1916. Larimar was classified in 1979 as a semiprecious stone.
